  • the window sill support profile adjoins the window support profile on the front side and is firmly and sealedly connected to it, that the window sill support profile consists primarily of a closed-cell insulating material and the window support profile consists primarily of a moisture-resistant plastic with a high compressive strength, wherein the moisture-resistant plastic of the window support profile is a recycled PET with a compressive strength of at least 1.15 MPa, preferably of at least 2.5 MPa, and wherein the compressive strength of the moisture-resistant plastic is higher than the compressive strength of the closed-cell insulating material of the window sill support profile.
  • the window sill substructure according to the invention preferably forms a prefabricated shaped body prepared for immediate installation in a building opening, comprising three main elements, namely the window sill support profile, the window support profile, and at least one side element.
  • the structure is placed on the lower crossbar of the building opening and preferably enables direct connection to the facade insulation.
  • the lower corner areas of the building opening are sealed due to the trough shape, and a second sealing layer is formed below the window sill to be installed.
  • the window sill substructure is already adapted to the width of the building opening.
  • the window sill support profile and the window support profile are directly adjacent to one another, without the interposition of further structural elements separating the profiles, in particular without a connecting web as in the DE 20 2019 104 202 U1
  • the window support profile transfers the load of the window directly into the lower crossbar of the building opening, while the window sill support profile essentially only has to absorb the load of the window sill.
  • the advantage of this construction according to the invention lies in the fact that an insulating material is used for the window sill support profile which, due to its closed-cell structure, fulfills the necessary properties for forming a second sealing layer beneath the window sill.
  • the material for the window support profile is selected based on strength criteria.
  • the window support profile is designed in such a way that it directly transmits forces into the underlying crossbar, and the window sill support profile is essentially not involved in this force transmission.
  • the compressive strength of the closed-cell insulating material is therefore correspondingly lower.
  • the side element ensures a watertight lateral closure of the tub shape and should therefore preferably be made of a moisture-resistant material.
  • the moisture-resistant plastic material of the window support profile is particularly sustainable because it can be produced, for example, from recycled PET bottles. This material is preferably used to produce extruded foam boards, which exhibit the desired high compressive strength in the extrusion direction.
  • outside refers to the window or door installed in the building opening.
  • front refers to the outside
  • rear refers to the inside.
  • significant means a volume fraction of more than 75%, preferably more than 85%.
  • closed-cell in the claims means that at least 95% of the cells of the foam material are closed. Open cells are primarily created by machining and thermal processing after extrusion, for example, by cutting the profiles to length.
  • the closed-cell insulation material of the window sill support profile is an XPS, preferably with a thermal conductivity of ⁇ 0.04 W/(mK), more preferably ⁇ 0.038 W/(mK) (according to DIN 4108-10).
  • the window sill support profile can therefore be provided as a profile with a corresponding cross-sectional shape.
  • the moisture-resistant plastic of the window sill support profile can have a density of ⁇ 30 kg/m 3 to ⁇ 75 kg/m 3. This guarantees a particularly high gas content within the closed-cell insulation material, resulting in good insulating properties.
  • the closed-cell insulation material of the window sill support profile can have a compressive strength at 10% compression of at least 200 kPa and a maximum of 900 kPa, preferably at least 280 kPa and a maximum of 720 kPa.
  • the compressive strength at 10% compression is usually determined in accordance with DIN EN 826, because these insulation materials always have a certain irreversible resilience due to their cellular structure, especially if some cells collapse under load.
  • the closed-cell insulation material of the window sill support profile is thermally treated, at least in the window sill support area, so that the surface in the treated area is smoothed and/or the surface pores are largely closed. This ensures that water running off the second sealing layer can be more effectively drained away, i.e., the flow resistance is reduced. If there are subsequently processed surface areas, for example, by cutting the extruded profile to length or creating grooves, etc., open surface pores can be closed again using the thermal treatment.
  • the at least one side element is formed from a flexible sealing film.
  • a flexible sealing film has advantages when transporting such window sill substructures in stacks. Furthermore, structural tolerances and structural settlement or deformation can be better accommodated. This enables precise adaptation to the side walls of the building opening in the lower corner areas.
  • the lateral sealing of the window frame towards the building opening can be achieved using a compression tape (preferably a closed-cell sealing tape), which can easily compensate for the thickness of the sealing film without any disadvantages in terms of sealing effectiveness. In the lower corner areas, the seal is even reinforced because the compression tape is subjected to somewhat greater compression by inserting the sealing film between the two.
  • the at least one side element is firmly and sealed laterally to both the associated lateral end face of the window sill support profile and the associated lateral end face of the window support profile. This simplifies the manufacture of the fastening of the side element because the side element only needs to be flanged to the other two profiles at the end face.
  • the side element can be formed flat for this purpose, and folding it around the edge areas of the two support profiles is also unnecessary.
  • a further embodiment provides for the side element to have a height such that the side wall of the trough shape formed by the side element projects at least 15 cm beyond a window support surface of the window support profile.
  • the side element is therefore extended upwards so far that it preferably projects above the lower stile of the window frame and the lower stile of the window frame above it, or at least ends flush with the upper edge of the lower stile of the window frame. This provides sufficient protection against water flowing over the window in the lower area.
  • a window support surface of the window support profile is designed flat and a closed-cell sealing tape is used for sealing between the window support profile and a window to be placed on the window support profile of the window sill substructure.
  • the window support profile should be designed in the area of the window support surface completely without closed grooves on the long sides.
  • a stepped shoulder can only be provided on the long side edges, as long as the rest of the window support surface is flat and without further contouring. This ensures that the window frame, which is usually made of an extruded profile, rests securely on the window support surface with its load-bearing profile webs. Due to the flat design of the window support surface, it can be used for a variety of different profile shapes of the window frame together with a geometrically simple shaped sealing strip.
  • a block-shaped supplementary element is arranged in the corner formed by the window sill support profile, the window support profile, and the side element.
  • the supplementary element rests on the window sill support profile, has a height that results from the height that the window support profile projects above the window sill support profile, has a width that results from the width of a reveal panel that is placed on the window sill support profile, and has a thickness that results from the projection that a window frame that is placed on the window support profile projects forward beyond the window support profile.
  • the block-shaped supplementary element therefore fills the gap that arises in the lower corner area of the tub shape between the protruding window frame and the window support profile.
  • the supplementary element is preferably glued in and extends the window support surface in the corner area to form an L-shape (in plan view).
  • one variant allows the window support profile to protrude at least 5 mm, preferably at least 20 mm, beyond the adjacent section of the window sill support profile, creating a corresponding offset (in height) between the window sill support profile and the window support profile.
  • the offset also depends significantly on the window sill to be used, for example, whether a stone window sill or an aluminum window sill is to be installed.
  • a further embodiment provides for a plaster connection profile to be attached to the front end area of the window sill support profile, which protrudes from the front side of the window sill support profile and which is inserted into a step of the window sill support profile is arranged in such a way that the underside of the plaster connection profile is flush with the top side of the window sill support profile or is offset slightly, preferably by a maximum of 2 mm, downwards compared to the top side of the window sill support profile.
  • a plaster connection profile usually has a drip nose so that water flowing over the second sealing level can drip down in front of the facade.
  • a drip nose can be made of an elastic material.
  • the specified arrangement of the plaster connection profile ensures that water can flow unhindered from the window sill support profile over the plaster connection profile.
  • the window sill support profile has a wedge shape in cross-section so that water drains outwards more easily.
  • the plaster connection profile is preferably attached to the front side of the window sill support profile in such a way that it takes up the inclination of this wedge shape and diverts water far enough that it does not penetrate directly into the exterior plaster.
  • a reinforcing mesh can be attached to the plaster connection profile and, with the window sill substructure installed and prior to plastering, hang downwards in front of the front of the window sill support profile, wherein the front of the window sill support profile has an offset step in most of the area of the reinforcing mesh such that in the area of the offset step there is a greater horizontal distance between the reinforcing mesh and the window sill support profile than in the area without an offset step.
  • the window sill support profile can advantageously have a height offset on the underside to form a support step whose recessed support surface merges flush with the underside of the window support profile.
  • the height offset interrupts the gap existing beneath the window sill substructure and, on the other hand, serves as a positioning aid when attaching the window sill substructure.
  • window sill substructure it is not necessary to assemble the window sill substructure from its individual components in the area of the building opening. Therefore, another design provides for the window sill substructure to be prefabricated and prepared for immediate, uniform insertion into a building opening.
  • This design is particularly advantageous when the widths of the building openings are specified or guaranteed. Relatively tight tolerances exist, particularly in prefabricated house construction, so this type of prefabrication is extremely beneficial. The installer simply needs to connect the window sill substructure to the lower crossbar of the building opening to ensure the desired precautions for suitable sealing in the lower corner area of the building opening.

  • the window sill substructure 1 can be manufactured in different lengths and widths.
  • the window support profile 7 has been designed to be suitable for a wide variety of windows 11 available on the market.
  • the weight of the window 11 is optimally transferred to the crossbar 4 by means of the window support profile 7.
  • excellent Insulation in the area of the window sill 20 and the provision of a second sealing layer Due to the materials selected for the individual elements of the window sill substructure 1 and the watertight connection of the elements to one another, a good seal is inevitably achieved in the lower corner area of the building opening 2.
  • a block-shaped supplementary element 45 is arranged in the corner area between the window sill support profile 6, the window support profile 7, and a side element 8.
  • the supplementary element 45 is glued to all three elements and sits on the window sill support profile 6. For this purpose, it is beveled at the bottom according to the inclination of the window sill support surface 19.
  • the height H E of the supplementary element 45 corresponds to the height by which the window support profile 7 projects above the window sill support profile 6.
  • the thickness D E of the supplementary element 45 corresponds to the projection Ü (see Figure 1 ), which the window frame 12 placed on the window support profile 7 protrudes forwards over the window support profile 7. As a result, the supplementary element 45 is flush with the outside of the window frame 12.
  • the width B E of the supplementary element 45 corresponds to the width of a reveal panel (not shown) to be placed on the window sill support profile 6.
  • the sealing in this area can be further improved by the supplementary element 50.
  • the Figures 4 and 5 The window sill substructure 1 shown can be installed in the same way as the one shown in Figure 1 shown variant can be inserted into the same building opening 2.
